Tall, dense clouds are called “cumulonimbus,” and they’re the type of clouds that form before and during a thunderstorm. They’re created when water vapor is boosted upward by air currents.
These tall and dense clouds are also known as “thunderheads.” When you see them, it’s time to head inside.
Brown or Muddy Water
If you’re looking at a stream that’s usually clear but now it looks muddy and brown, it could mean that a flood is on its way.
Water can become brown and muddy when sediment breaks loose and becomes swept up by sudden influxes of water.
If Metal Objects Start to Vibrate
Metal objects aren’t supposed to vibrate, buzz, or crackle. If this is happening, then that means that the area you’re in could be struck by lightning.
The metal object is getting charged by the electricity in the air. If possible, you should go inside immediately. If you can’t, get as close to the ground as possible while avoiding any tall structures.
When Streams Change Direction
When people say streams and rivers change direction when there’s an earthquake — that’s actually true! Sometimes, streams change direction during an earthquake.
Even larger rivers can be impacted! So if you notice a stream or river changing direction, it could signal something's about to happen. Scary, but it’s also a little cool, right?
Yes, you read that right! Sudden headaches can be a sign that nature is about to strike. You can get headaches when the barometric pressure drops from an incoming storm or hurricane.
Hurricanes usually happen around 30 to 36 hours before the actual storm hits land. Low barometric pressure can also cause low blood pressure.
